This article shows how to create a fading/dimming effect of the LED using PIC micro-controller. For similar design based on Arduino click this link.Controlling LED brightness using PWM is a relatively simple task and can be accomplished by configuring PIC16F877 ...

Vacuum fluorescent display can be a good alternative to a Liquid-crystal displays in some applications. They have a number of advantages over LCD like extended temperature range and excellent contrast in high brightness environment. The main disadvantage is higher power consumption ...

MAX7219 is a common cathode display driver with a simple serial interfaces that can be easily connected to a microcontroller. Among other useful features this IC has built in brightness control and scan control capability that allows to limit the ...

In this post I’m going to show you how to interface an I2C Real Time Clock – RTC with PIC microcontroller. Only a basic hardware configuration and a communication protocol are presented here. I’m planning to extend it to a ...

This is an upgrade to recently published Simple Digital Voltmeter.Few improvements were done to hardware and software.DVM operating range  was slightly increased up to 24 V Max, however the most significant change is that the code now uses full 10 bit of ...

In this post a simple Digital Dual Voltmeter and Ampere meter design will be shown. It uses PIC16F876A microcontroller and 2x16 LCD display and has 2 input channels for measuring voltage in 0-25v range and current up to 500mA. The ...

3 Digit Up Down Counter shown here is based on PIC16F877A microcontroller. The count is shown on the 2x16 LCD display and the direction is controlled by a switch connected to bit 3 of PORTA. With minimal changes the attached ...

Fan Speed Monitor is another simple design based on PIC16F876A microcontroller. Two similar posts about ways of controlling and monitoring fan speed were recently published. PWM Fan Controller and 2 Channel PC Fan Controller. Current article however implements a different ...

This is PIC16F877A microcontroller based digital clock with 7-Segment display. For this project LTC3710HR was used, however the schematic can be easily adjusted to incorporate larger displays.LTC3710HR is 0.3 inch quadruple digit multiplex common cathode display.Main consideration for choosing the display ...

In this article I’ll demonstrate a digital stopwatch design based on PIC16F876A micro controller.For related circuit based on Arduino click here. Similar project showing a Digital Timer design can be found here. Current circuit can be used to count in ...
